TECHNICAL FIELD

The present invention relates to a refrigerator, more specifically to arefrigerator including a main body housing a fresh food compartment, anda cool air duct provided in a wall of the fresh food compartment andhaving cool air discharge openings opened toward the fresh foodcompartment to supply a cool air from an evaporator into the fresh foodcompartment.

BACKGROUND ART

As described in FIG. 1, a conventional refrigerator has a thermallyinsulated main body 4 housing a freezing compartment 2 and a fresh foodcompartment 3 separated with each other by a partitioning wall 1, aswell as a freezing compartment door 6 and a fresh food compartment door7 which open/close the freezing compartment 2 and the fresh foodcompartment 3 respectively. In the main body 4 of the refrigerator isinstalled a refrigeration system consisting of a compressor 11, acondenser(not shown), an evaporator 12a for the freezing compartment 2and an evaporator 12b for the fresh food compartment 3. A cool airproduced at each evaporator 12a, 12b is directed toward the freezingcompartment 2 and fresh food compartment 3 by means of the freezingcompartment fan 13a or the fresh food compartment fan 13b.

In the back wall of the fresh food compartment 3 is disposed a fan 13b.The cool air duct 15 has cool air discharging openings 16 facing theinterior of the fresh food compartment 3 through which the cool air isprovided to the compartment 3. A control damper 19 closing/opening theentrance of the cool air duct 15 is provided at the entrance of the coolair duct 15 in order to control the amount of cool air blown into thefresh food compartment 3.

In the typical refrigerators, the cool air for the fresh foodcompartment 3 is generally delivered in a so-called shelf-by-shelffashion as illustrated in FIG. 2. In a shelf-by-shelf cooling method,the fresh food compartment 3 is stratified by means of shelves 8 intoseveral sub-compartments, and the vertically arranged cool airdischarging openings 16 are associated to the sub-compartments toprovide the cool air to the respective corresponding sub-compartment.

However, the refrigerator adopting the above shelf-by-shelf coolingmethod are burdened with a problem of an uneven refrigeration in thefresh food compartment 3, due to a temperature difference betweenregions of the fresh food compartment 3. Since the cool air is blowninto the compartment 3 only in the direction toward which thedischarging openings 16 is facing, there is bound to exist a regionwithin the compartment 3 receiving more cool air or less than others.Furthermore such a cooling method does not allow the flexibility toconcentrate the cool air into a specific region when there is anecessity to have a region cooler than others.

A so-called tri-dimensional refrigerator has been recently conceived toovercome the forementioned shortcoming of the shelf-by-shelf coolingmethod. As illustrated in FIG. 3, in such a method, a number of cool airdischarging openings 16' are located not only on the back wall but alsoon the side walls of the fresh food compartment 3 allowing the deliveryof the cool air from three sides.

Such a tri-dimensional cooling method, despite an improved uniformdistribution of cool air in the fresh food compartment 3 however, doesnot permit the cool air to be fully dispersed in the compartment 3 asthe discharge of the cool air is effectuated only in fixed directions.Foodstuffs stored in a region where the cool air is mainly directed havea risk of being over-cooled. By contrast, foodstuffs scored in thecorners may not be cooled sufficiently. Accordingly, in the method,there's a definite limit in maintaining the temperature even throughoutthe storage area. Furthermore, as in the case of the shelf-by-shelfcooling system, this method makes impossible to concentrate the cool airinto a specific area, should there exist a necessity to do so. A furthersignificant problem of the tri-dimensional cooling method is that arefrigerator equipped with such a system is expensive to produce (extraparts and extra manufacturing cost) as additional ducts need to beinstalled at the side walls of the fresh food compartment 3.Furthermore, such a refrigerator has yet another disadvantage of areduced storing capacity as the walls need to be thicker. Moreover, theenergy loss in the cool air flow becomes more significant.

The above mentioned problems become a real issue with today's trend ofincreasingly larger refrigerators. In high capacity refrigerators whichnecessitate larger dimensions, there is a definite limit in distributingthe cool air evenly to all regions in the fresh food compartment 3. Asillustrated in FIG. 1, since each cool air discharging opening 16 isformed perpendicularly to the direction of the flow of the cool air, thecool air coming from the evaporator 12b is not evenly distributed amongthe discharging openings 16. The lower the discharging opening 16b is,the more cool air is distributed to. As a consequence, a uniformdistribution of cool air in the fresh food compartment 3 in a verticaldirection can not be achieved, resulting in the over-cooling of thefoodstuffs stored at the bottom, and under-cooling of those foodstuffsstored at the top.

In order to solve the forementioned problems, a refrigerator has beenproposed in International Patent Publication WO 95/27178 by theapplicant of this invention. The refrigerator is equipped with a coolair dispersing device which distributes the cool air from the cool airduct evenly to all regions of the fresh food compartment, as illustratedin FIGS. 4 to 7.

FIG. 4 is a side cross-sectional view of a refrigerator equipped with acool air dispersing device, and FIG. 5 is a partially enlarged view ofthe refrigerator in FIG. 4. As in the conventional refrigerator of FIG.1, the refrigerator consists of a main body 14, a compressor 31,evaporators 32a, 32b and fans 33a, 33b. In the rear wall of the freshfood compartment 23 is provided a cool air duct 34 through which thecool air from the fresh food compartment evaporator 32b flows down afterbeing blown therein by the fresh food compartment fan 33b. Inside thiscool air duct 131 is disposed a cool air dispersing device 40 in avertical arrangement. In the rear wall of the fresh food compartment 23are disposed a cool air discharging openings 34 through which the coolair from the cool air duct 34 is discharged into the fresh foodcompartment 23. The cool air dispersing device 40 guides the providedcool air into the fresh food compartment 23 through these cool airdischarging openings 36. In the rear of the cool air duct 34 is disposeda circulation duct 28 connecting the fresh food compartment 23 and thefresh food compartment evaporator 32b in such a way that the circulationduct 28 is isolated from the cool air duct 34. The cool air, aftercooling the fresh food compartment 23, is returned to the fresh foodcompartment evaporator 32b via the circulation duct 28.

The cool air dispersing device 40, as illustrated in FIG. 6, iscomprised of a rotary shaft 41, and a plurality of cool air dispersingwings 45. The rotary shaft 41 is installed at the surface of the rearwall of the fresh food compartment 23 in such a way as to allow it torotate freely. To the upper part of the rotary shaft 41 is connected adriving motor 38 which enables the rotation of the shaft 41. The coolair dispersing wings 45 have a waved strip shape waved to a planeincluding the rotational axis of the rotary shaft 41. The wings 45 aredistanced out from each other along the length of the shaft 41 and aredisposed as to correspond to the positions of the cool air dischargingopenings 36. At the upper and lower end of each cool air dispersing wing45 are disposed end discs 43 including upper and lower disc 43a and 43brespectively. Furthermore, between the discs 43a and 43b is disposed amiddle disc 44 which bisects the cool air dispersing wing 45 into afirst wing portion 45a and a second wing portion 45b. Each wing portion45a, 45b is curved in such fashion as to have a an "S" shapedcross-section. Within a single cool air dispersing wing 45, the "S"shape of the upper and lower wing portions 45a and 45b are reversed toeach other.

When the driving motor 38 rotates the rotary shaft 41 at low speed, thecool air supplied through the cool air duct 34 changes its direction offlow according to the curved surface of the cool air dispersing wings45; and as depicted in FIG. 7, the cool air is blown into the fresh foodcompartment 23, dispersed to the left and right directions. An evendistribution of the cool air in the right and the left side of the freshfood compartment 23 is achieved, and the cool air can be concentrated toone specific region by fixing the cool air dispersing wing's 45 facingdirection by stopping the rotation of the rotary shaft 41. It is by sucha cool air dispersing device 40 that an evenly distributed refrigerationor a concentrated refrigeration are realized in the fresh foodcompartment 23.

Although the above cool air dispersing device 40 allows the refrigeratorto achieve an even distribution of the cool air in the horizontaldirection, it does not allow an even distribution of the cool air in thevertical plane. In other words, the above cool air dispersing device doallow a left-right dispersion of the cool air, but do not allow anup-down dispersion of the cool air, falling a little short fromrealizing an even distribution of the cool air in the whole fresh foodcompartment 23.

DISCLOSURE OF INVENTION

Accordingly, the object of the present invention is to provide arefrigerator in which an even refrigeration in a fresh food compartmentis realized by an even discharge of a cool air from an evaporator in theleft, right, up and down directions, and in which it is possible toconcentrate all the cool air into a specific region should a need arise.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the present invention will be described in detail withreference to the drawings.

FIG. 8 is a side cross-sectional view of a refrigerator equipped with acool air dispersing device according to the present invention. Asillustrated, the refrigerator according to the present invention, as inconventional refrigerators, has a thermally insulated main body 64housing a freezing compartment 62 and a fresh food compartment 3separated with each other by a partitioning wall 61, as well as afreezing compartment door 66 and a fresh food compartment door 67 whichopen/close the freezing compartment 62 and the fresh food compartment 63respectively.

In the fresh food compartment 62 are disposed a plurality of shelves 68which stratify the compartment 63 into several storage areas. A specialsub-compartment 63a is disposed at the upper region of the fresh foodcompartment 63 for foodstuffs which require to be stored in a specifictemperature. At the bottom of the fresh food compartment 63 is located avegetables compartment 63b for storing vegetables.

In the main body 64 of the refrigerator is installed a compressor 71, acondenser(not shown) as well as a freezing compartment evaporator 72aand a fresh food compartment evaporator 72b which together perform arefrigeration cycle. The cool air is produced at each evaporator 72a,72b. Directly above each evaporator 72a, 72b are disposed a fan 73a forthe freezing compartment 62 and a fan 73b for the fresh food compartment63 which forcefully blow the cool air produced at the evaporators 72a,72b into the fresh food compartment 63 or the freezing compartment 62.

In the rear wall of the fresh food compartment 63 is provided a cool airduct 131 in which is disposed a cool air dispersing device 80. The coolair blown into the cool air duct 131 by the fan 73b of the fresh foodcompartment 63 is further delivered into the fresh food compartment 63via the cool air dispersing device 80. In the rear of the cool air duct131 is disposed a circulation duct 74 connecting the fresh foodcompartment 63 and the fresh food compartment evaporator 72b in such away that the circulation duct 74 is isolated from the cool air duct 131.The cool air, after cooling the fresh food compartment 63, is returnedto the fresh food compartment evaporator 72b via the above circulationduct 74.

FIG. 9 is an enlarged side cross-sectional view of the duct housing 100which is installed in the rear wall of the fresh food compartment 63 andconstitutes the cool air duct 131. FIG. 10 is an exploded perspectiveview of FIG. 9. The duct housing 100 forming the cool air duct 131 iscomprised of a duct member 130 which guides insulatedly the cool air, afrontal panel 120 which covers up the front side of the duct member 130,a seal panel 150 which covers up the rear side of the duct member 130and a partially cylindrical cool air grill member 110 which surroundsthe cool air dispersing device 80 at the front side of the frontal panel120. In the cool air grill member 110 are formed the cool airdischarging openings 36 facing the fresh food compartment 63. The coolair dispersing device 80 is rotatably installed on the frontal panel120. The frontal panel 120 and the duct member 130 are formed withrecesses 121, 121' for accommodating a portion of the cool airdispersing device 80 to surround the cool air device 80 in cooperationwith the cool air grill member 110.

The cool air dispersing device 80 is comprised of a vertically disposedrotary shaft 85, and cool air dispersing wing pairs 81, 82 which aredisposed along the shaft 85 at locations corresponding to the cool airdischarging openings 36. The device 80 is put into rotation by means ofa driving motor 125 housed in a motor case 124 located in the upper partof the frontal panel 120. It is desirable that the driving motor 125 isof a stepping motor to allow angle-controlled stops and reverserotation. At each side of the driving motor 125 is disposed a lamp 127for the purpose of illumination which is switched on and off accordingto the open/closed state of the fresh food compartment door 67. A lampcover 126 houses each lamp 127.

The cool air grill member 110 is installed at the recess 121, 121' ofthe frontal panel 120. The cool air discharging openings 36 on the grillmember 110 are disposed in such a way as to correspond to the positionsof the cool air dispersing wings 81 of the cool air dispersing device80. The frontal panel 120 is installed virtually conforming with theinner surface of the rear wall of the fresh food compartment 63, and thecool air grill member 110 is installed in such a way as to protrude fromthe frontal panel 120 out to the inside of the fresh food compartment63. Accordingly, the grill member 110 and the cool air dispersing device80 as a whole protrude somewhat from the rear wall surface of the freshfood compartment 63; this allows the cool air delivered by the cool airdispersing device 80 to be distributed in the compartment 63 in a wideangle.

In the upper part of the duct member 130 is disposed a conducting path132 into which the cool air produced at the evaporator 72b is directed.Inside this conducting path 132 is installed a control damper 79 whichregulates the amount of cool air flowing into the path 132 byopening/closing this path 132. At the upper portion of the duct member130 is located cool air vents 133 for the special sub-compartment 63a,extending out of the conducting path 132 into the front surface of theduct member 130. The cool air vents 133 communicate with cool airdischarging openings 123 for the special sub-compartment 63a, which aredisposed in the frontal panel 120. The cool air discharging openings 123for the special sub-compartment 63a face and provide the cool air to theinterior of the special sub-compartment 63a in the fresh foodcompartment 63.

FIG. 11 is a rear perspective view of FIG. 9 showing the coupled stateof the duct member 130 and the frontal panel 120. The rear surface ofthe duct member 130 is formed with a plurality of cool air guides 137,and between these guides 137 are disposed cool air directing vents 138which pass through the duct member 130. The cool air directing vents 138are positioned to correspond to the locations of the dispersing wings 81of the cool air dispersing device 80.

The cool air ducts 131 are formed vertically at the rear surface of theduct member. The cool air guides 137 divides the cool air ducts 131 intoa first duct portion 131a and a second duct portion 131b at each sidethereof. The two duct portions 131a, 131b are met by the conducting path132 at the upper end, and by the vegetables compartment 63b at the lowerend.

Each duct portion 131a, 131b is directed into the cool air directingvent 138 through a first connecting channel 135a and a second connectingchannel 135b which are formed between the cool air guides 137. In theillustrated embodiment, three cool air directing vents 138 are providedat the upper, middle and lower regions, and three sets of the connectingchannels 135a and 135b are disposed to correspond to the positions ofthe cool air vents 138. Each connecting channel 135 has its upperportion rounded and its lower portion wider to the exterior than theupper portion, thereby allowing the cool air flowing down the ductportion 131 to be dispersed and directed to the connecting channels 135in a natural fashion. The lower connecting channel is wider to theexterior and has a larger entrance than the middle connecting channelwhich is in turn wider than the upper connecting channel, thus allowingan even distribution of the cool air flowing into each respective coolair directing vent 138. The seal panel 150 is attached airtight to theduct member 130, and forms the rear wall of the cool air duct 131. Theduct member 130 and the seal panel 150 are made out of insulatingmaterials such as polystyrene foam and minimize the heat transfer lossof the cool air.

FIG. 12 is a partially enlarged perspective view of the cool airdispersing wing pairs 81, 82 of the cool air dispersing device 80corresponding to one cool air discharging opening 36. The cool airdispersing device 80 is comprised of a rotary shaft 85, a partitioningplate 83 mounted on the rotary shaft 85 along the axis of rotation, andcool air dispersing wing pairs 81, 82 which are attached to bothsurfaces of the partitioning plate 83. A connecting hole 86 is disposedat the upper distal end of the rotary shaft 85 for the connection of thedriving shaft of the motor 125.

The virtually rectangular partitioning plate 83 is disposed verticallyalong a plane which contains the axis of rotation of the rotary shaft85. At the upper and lower ends of the partitioning plate 83, andtransversely to the rotational axis, are mounted end plates 87, 89 of adisc shape. Another disc plate, a middle plate 88, is disposed in themiddle between end plates 87, 89. The middle plate 88 divides thepartitioning plate 83 into the upper and lower partitioning plates 83aand 83b. The partitioning plates 83a, 83b have a "S" shape and a reverse"S" shape in cross-section respectively, or vice-versa.

The upper pair of cool air dispersing wings 81 is attached to both sidesof the upper partitioning plate 83a, and the lower pair of cool airdispersing wings 82 is attached to both sides of the lower partitioningplate 83b. Each pair of wings 81, 82 can be further broken down into afirst wing 81a, 82a and a second wing 81b, 82b. The wings 81a, 81b, 82a,82b, are disposed at a predetermined incline to the rotary shaft 85,with the slopes of the first wings 81a, 82a exactly opposite to theslopes of the second wings 81b, 82b. Furthermore, the wings of the upperwing pair 81 and the lower wing pair 82 which are on the same side ofthe partitioning plate are disposed so that their inclined angles ofincidence at the partitioning plate 83 oppose to each other.Furthermore, each wing 81a, 81b, 82a, 82b are disposed in such a way asto leave a gap to the upper end plate 87, the middle plate 88 and thelower end plate 89.

In such an arrangement, the cool air conducted from the cool air vent138 to the cool air dispersing device 80, is directed to the fresh foodcompartment 68, while being dispersed to up, down, left and rightdirections by being guided by the surfaces of the wings 81a, 81b, 82a,82b. Moreover, there exits a current of the cool air discharged in astraight direction without hitting any wing surface as there is roombetween the individual wings 81a, 81b, 82a, 82b and the plates 87, 88,89. The angle at which the cool air is discharged into the fresh foodcompartment is dependent upon the angular position of the rotary shaft85, which means that as the driving motor 125 rotates the shaft 85, thecool air is dispersed evenly to all directions(left, right, up anddown); and the cool air can be concentrated to one single specificdirection by stopping the rotary shaft 85 from rotating.

Inside the fresh food compartment 63, as illustrated in FIG. 13, aredisposed a plurality of temperature sensors 140. The refrigerator sensesthe temperature of the fresh food compartment 63 through these sensors140 and if the temperature in the compartment 63 is not appropriate tothe refrigeration power level desired by the user, the compressor 71 isactivated and the refrigeration operation is put into effect.Accordingly, the cool air produced in the fresh food compartmentevaporator 72b passes through the control damper 79 and then to theconducting path 132; the cool air is then dispersed to the left and tothe right by the cool air guides 137. The cool air is drained down, anddischarged into the fresh food compartment 63 and the vegetablescompartment 63b via the first and the second duct portions 131a and131b. A portion of the cool air is blown into the specialsub-compartment 63a through the cool air vents 133 and through the coolair discharging openings 123.

In order to achieve an uniform distribution of the cool air in the freshfood compartment 63, the cool air dispersing device 80 rotates by meansof a driving motor 125, and the cool air provided thereat flowsaccording to the sloped surfaces of each of the wings 81a, 81b, 82a, 82band is dispersed to all directions(left, right, up and down) in thefresh food compartment 63 as illustrated in FIG. 13. As a result, auniform temperature is achieved within the fresh food compartment 63eliminating regions that are normally deprived of cool air.

The cool air dispersing device 80 can change the direction of its coolair discharge by shifting its angular position of its rotation. Anuniform distribution of cool air in all directions is realized thanks tothe continuously changing angle of discharge of the cool air created bythe slowly rotating cool air dispersing device 80 powered by a drivingmotor 125. Furthermore, as the temperature of a specific region withinthe fresh food compartment 63 goes up for such reasons as storing a hotitem, the driving motor 125 can lock the discharge angle of the cool airdispersing device 80, in order to concentrate all the cool air in thatparticular direction and effectuate a concentrated refrigeration of theregion.
